Abstract
A liquid crystal device is constituted by disposing a liquid crystal layer between a pair of oppositely disposed substrates each provide with an electrode in the form of stripes. The liquid crystal layer comprises a liquid crystal disposed in a region which is enclosed by the pair of substrates and a sealing agent disposed so as to form a peripheral wall having an injection port. The liquid crystal device has an effective optical modulation region and a peripheral region, including the injection port other than the optical modulation region. On at least one substrate, at least one elongated projection having a height smaller than a thickness of the liquid crystal layer is formed in the peripheral region including the injection port and in a direction parallel to the stripe electrode on the same substrate and perpendicular to a liquid crystal injection direction.
